FIG. 1A shows an example of the configuration of the discharge device 100 . The discharge device 100 includes a first supply unit 10 , a second supply unit 20 , a storage unit 30 , and a discharge unit 40 . The discharge device 100 discharges the contents of the aerosol container 150 accommodated in the storage unit 30 . The storage unit 30 of this example accommodates two aerosol containers, an aerosol container 150a and an aerosol container 150b.

The aerosol container 150a is filled with the first content 12 and functions as a pressure source. The first content 12 may also be liquefied gas or compressed gas. The aerosol container 150a is an example of the first aerosol container filled with the first content 12 . The aerosol container 150a and the aerosol container 150b in this example are metal aerosol cans, but they may also be pressure-resistant plastic containers. The first content 12 and the second content 22 are described later.

The aerosol container 150b is an example of a second aerosol container filled with a second content 22 different from the first content 12 . The aerosol container 150b ejects the second content 22 such as liquid by the gas pressure of the liquefied gas or compressed gas filled inside. The propellant of the aerosol container 150b may also be a liquefied gas that has not been dissolved in the second content 22 . In addition, the aerosol container 150b may be an external BOV (Bag on Valve, bag on valve) system in which the content is stored inside the inner bag and the propellant is stored in the inner bag. For example, the aerosol container 150b contains a Freon substitute as a propellant, and contains paint as a second content 22 .

In addition, as the propellant of the first content 12 and the second content 22 , a known gas used in general aerosol products can be used. The liquefied gas may be propane, butane, pentane, or liquefied petroleum gas containing these substances, dimethyl ether, hydrofluoroolefins, hydrofluorocarbons, etc., or a mixture of a plurality of these substances may be used. In addition, examples of compressed gas include nitrogen, carbon dioxide gas, compressed air, oxygen, helium, laughing gas, and the like, and a plurality of these may be mixed and used.

The first supply unit 10 functions as a gasification chamber for gasifying the first content 12 supplied from the aerosol container 150a. The first supply part 10 has a volume of sufficient size to vaporize the first content 12 . The internal pressure of the first supply part 10 is increased by vaporization of the first content 12 . The shape of the first supply part 10 in this example is cylindrical, but it is not limited thereto. The discharge device 100 may include a plurality of first supply units 10 . A plurality of first supply parts 10 may also be connected to one airgel container 150a. By arranging a plurality of first supply parts 10, the surface area of the first supply part 10 is increased and heat exchange is facilitated, thereby making the first content 12 easy to vaporize.

The first connection part 14 connects the aerosol container 150 a and the first supply part 10 . The first connecting portion 14 in this example penetrates the housing portion 30 and connects the inside and the outside of the housing portion 30 . In addition, the shape of the first connection part 14 is not limited to this example, as long as it connects the aerogel container 150 a and the first supply part 10 .

The second supply unit 20 is connected to the aerosol container 150b. The second content 22 is poured into the second supply part 20 . Also, the second supply unit 20 is connected between the first supply unit 10 and the discharge unit 40 . The second content 22 injected into the second supply unit 20 is discharged from the discharge unit 40 by the first content 12 vaporized in the first supply unit 10 . Although the shape of the second supply part 20 of this example is cylindrical, it is not limited to this. The discharge device 100 may include a plurality of second supply units 20 .

The second connection part 24 connects the airgel container 150b and the second supply part 20 . The second connection part 24 injects the second content 22 into the second supply part 20 from the side of the first supply part 10 to the side of the discharge part 40 of the second supply part 20 . The discharge device 100 may include a plurality of second connecting parts 24 . The second connection part 24 in this example includes a second connection part 24a, a second connection part 24b, and a second connection part 24c which are connected to each other.

The second connecting portion 24 a penetrates the housing portion 30 and connects the inside and the outside of the housing portion 30 . The second connection portion 24b is provided to extend straight from the second connection portion 24a. The second connection portion 24c is provided to extend from the second connection portion 24b toward the inside of the second supply portion 20 . The second connection part 24 c may be connected closer to the discharge part 40 than the first supply part 10 in the second supply part 20 . In addition, the second connection part 24c may be connected to the second supply part 20 so as to form an acute angle so as to inject the second content 22 toward the discharge part 40 side. Thereby, the reverse flow of the second content 22 to the first supply part 10 can be avoided.

The discharge unit 40 discharges the second content 22 of the aerogel container 150b. The discharge unit 40 is connected to both the aerosol container 150a and the aerosol container 150b. The discharge part 40 discharges the second content 22 by the pressure of the first content 12 . An example of the discharge unit 40 is a nozzle for discharging the contents. The discharge unit 40 has a discharge port for discharging the contents of the aerosol container 150 .

Here, the shapes of the first supply part 10 and the second supply part 20 may be appropriately changed according to the contents of the aerosol container 150 and the required characteristics of the discharge device 100 . In one example, the inner volume of the first supply unit 10 may be larger than the inner volume of the second supply unit 20 . By increasing the internal volume of the first supply unit 10, the first content 12 discharged from the aerosol container 150a is easily gasified. The cross-sectional area of the first supply unit 10 on the YZ plane may be made larger, and the length in the X-axis direction may be made longer.

The cross-sectional area of the first supply unit 10 may be larger than the cross-sectional area of the second supply unit 20 . By making the cross-sectional area of the first supply part 10 larger, the first content 12 discharged from the aerosol container 150a can be easily gasified. In addition, by making the cross-sectional area of the second supply part 20 small, the second content 22 can be easily discharged by the internal pressure from the first supply part 10 . In one example, by making the cross-sectional area of the second supply part 20 small, it is possible to prevent air bubbles from being generated when the second content 22 is supplied toward the second supply part, and to enable smooth discharge.

The discharge driving unit 90 supplies driving force to discharge the content from the aerosol container 150 . The discharge driving unit 90 of this example generates a driving force from the bottom side of the aerosol container 150 toward the valve stem side (that is, from the negative side toward the positive side in the X-axis direction). The discharge drive unit 90 of this example is housed in the housing part 30 . The discharge driving part 90 has a cam 91 , a cam follower 92 , a movable part 93 , and a cam coupling part 94 .

The discharge driving part 90a discharges the first content 12 from the aerosol container 150a. The discharge drive unit 90a is an example of a first discharge drive unit. The discharge drive part 90a of this example has the cam 91a, the cam follower 92a, the movable part 93a, and the cam connection part 94a.

The discharge driving part 90b discharges the second content 22 from the aerosol container 150b. The discharge drive unit 90b is an example of a second discharge drive unit. The discharge drive part 90b of this example has the cam 91b, the cam follower 92b, the movable part 93b, and the cam connection part 94b.

The discharge drive unit 90a and the discharge drive unit 90b may be independently driven. In one example, the discharge drive unit 90a and the discharge drive unit 90b discharge the contents at different timings from each other. For example, the second content 22 may not be discharged from the aerosol container 150b by the discharge drive unit 90b while the first content 12 is discharged from the aerosol container 150a by the discharge drive unit 90a. On the other hand, the second content 22 may be discharged from the aerosol container 150b by the discharge drive unit 90b while the first content 12 is not discharged from the aerosol container 150a by the discharge drive unit 90a.

In addition, the discharge drive unit 90a may discharge the first content 12 after the discharge drive unit 90b discharges the second content 22 . It is also possible to repeatedly discharge from the aerosol container 150a and the aerosol container 150b. In addition, the discharge period from the aerosol container 150a and the aerosol container 150b may be repeated.

In addition, the discharge drive part 90a and the discharge drive part 90b may have a part of common structure. The air discharge driving part 90 a and the discharge driving part 90 b may include a common movable part 93 or a common cam coupling part 94 .

The cam 91 is rotationally driven by a drive source such as a motor connected to the cam connection portion 94 . The cam 91 has a structure in which the distance from the rotation center to the outer periphery is different. The cam 91 is in contact with the cam follower 92 on the outer periphery. By changing the position of the cam follower 92 corresponding to the shape of the cam 91 , the opening and closing of the valve of the aerosol container 150 can be controlled. In addition, the shape of the cam 91 of this example is shown exaggeratedly.

The cam follower 92 is provided between the cam 91 and the movable part 93 . The cam follower 92 connects the cam 91 and the movable part 93 and transmits the rotational motion of the cam 91 to the movable part 93 in a linear motion. The cam follower 92 moves linearly according to the difference in the distance from the rotation center to the outer periphery of the cam 91 .

The movable part 93 is arranged to be in contact with the bottom surface of the aerosol container 150 to control the opening and closing of the valve of the aerosol container 150 . The movable part 93 advances and retreats on the X-axis by the cam follower 92 . For example, when the distance between the center of rotation of the cam 91 and the contact area of the cam 91 is short, the contact area abuts against the cam follower 92, and the movable part 93 retreats relative to the aerosol container 150 to close the aerosol container 150. valve. On the other hand, when the distance between the center of rotation of the cam 91 and the contact area of the cam 91 is long, the contact area abuts against the cam follower 92, and the movable part 93 advances relative to the aerosol container 150 to open the aerosol container. 150 valves.

The cam connection part 94 is connected to the cam 91 and rotates the cam 91 in a predetermined direction. The discharge device 100 of this example includes the cam connection part 94a connected to the cam 91a, and the cam connection part 94b connected to the cam 91b. The cam 91a and the cam 91b may be connected to the common cam connection part 94, and may be driven interlockingly at predetermined timing.

In addition, although the discharge drive part 90 has the structure which converts the rotational motion of a motor into linear motion by a cam mechanism, it is not limited to a cam mechanism. For example, the mechanism of the discharge drive part 90 may utilize the structure which converts the rotary motion of a motor into linear motion, such as a feed screw mechanism, a rack and a pinion, etc. As a drive source, not only a rotary motor but also a linear motor for linear drive, an air cylinder, an electromagnetic solenoid, and the like may be provided.

The discharge device 100 of this example is equipped with an aerosol container 150a serving as a pressure source and an aerosol container 150b serving as a liquid source side, respectively. Furthermore, in the discharge device 100, the internal pressure of the first supply part 10 is higher than the internal pressure of the second supply part 20 by the supply of the first content 12, thereby discharging the liquid that has been injected into the second supply part 20 from the discharge part 40. The second content 22 of 20.

Thereby, the discharge device 100 can exchange the aerosol container 150a and the aerosol container 150b separately. That is, it is possible to exchange only the aerosol container with a small residual amount individually. For example, the aerosol container 150a serving as a pressure source can be replaced according to consumption, so it is easy to maintain a constant pressure at the time of discharge. Further, the discharge device 100 of the present example does not need to set the aerosol container 150b as the liquid source side to a high pressure, so it is possible to reduce the spraying agent to be filled in the aerosol container 150b and increase the filling amount of the second content 22. .

Moreover, even if the second content 22 is a material that is compatible with the liquefied gas, the discharge device 100 is extremely limited because the first content 12 touches the second content 22 after it is vaporized. A change in the physical properties of the second content 22 can be suppressed toward the dissolution of the second content 22 . In addition, when the liquefied gas has been dissolved in the second content 22, the liquefied gas under the atmospheric pressure will vaporize rapidly, so the second content 22 becomes misty; In 100, it is possible to avoid becoming misty and keep the second content 22 flying out in a liquid state, thereby extending the flying distance of the second content 22 .

FIG. 1B is an example of a flowchart showing the operation of the discharge device 100 . In step S100, an aerosol container 150a and an aerosol container 150b are provided. In step S200 , inject the second content 22 into the second supply part 20 .

In step S300 , the first content 12 is supplied to the first supply unit 10 . For example, step S300 may include a stage of supplying the liquefied gas contained in the aerosol container 150 a to the first supply unit 10 . The step S300 of supplying the first content 12 to the first supply unit 10 may also be performed after the step S200 of injecting the second content 22 into the second supply unit 20 .

In step S400 , the second content 22 is discharged from the discharge unit 40 . In step S400, the internal pressure of the first supply part 10 is made higher than the internal pressure of the second supply part 20 by the first content 12, so that the second content injected into the second supply part 20 is discharged from the discharge part 40 Object 22.

In addition, the discharge apparatus 100 may implement step S200 - step S400 repeatedly. That is, the dispensing device 100 may also repeatedly implement the step S200 of dispensing the second content 22 from the aerosol container 150b by the dispensing drive unit 90b and the dispensing of the first content from the aerosol container 150a by the dispensing drive unit 90a. Step S300 of 12, whereby the second content 22 is intermittently discharged from the discharge unit 40 .

FIG. 2A shows an example of the operation of the discharge device 100 in step S200. In the discharge device 100 of this example, the second content 22 is poured into the second supply part 20 from the second connection part 24 . In this example, the second content 22 discharged from the aerosol container 150 b is poured into the second supply part 20 through the second connection part 24 .

The second content 22 can also be filled and injected into the second supply part 20 so that the internal pressure generated by the first content 12 cannot be avoided. The second content 22 can also be injected into a position separated from the first supply part 10 so as not to flow backward toward the first supply part 10 . In addition, the second content 22 can also be injected into a position away from the discharge part 40 so that the liquid does not leak from the discharge part 40 .

The distance Lf represents the distance from the connection position of the second supply part 20 and the second connection part 24 to the discharge part 40 in the X-axis direction. The distance Lb represents the distance from the connection position of the second supply part 20 and the second connection part 24 to the first supply part 10 in the X-axis direction. In this example, the distance Lf and the distance Lb are respectively set to a predetermined size or more in accordance with the material of the second content 22, the structure of the second supply unit 20, and the like. The distance Lf may be greater than the distance Lb.

In addition, the second supply part 20 and the second connection part 24 can also be detached from the first supply part 10 . Thereby, the second supply part 20 and the second connection part 24 contaminated by the second contents 22 can be easily exchanged. In addition, the second supply part 20 and the second connection part 24 having appropriate structures may be selected according to the second content 22 .

FIG. 2B shows an example of the operation of the discharge device 100 in step S400. When the first content 12 is supplied to the first supply unit 10 , the second content 22 is discharged from the discharge unit 40 . The discharge device 100 of this example discharges the second content 22 injected into the second supply part 20 by using the first content 12 of the pressure source. Thereby, the vaporized first content 12 is replaced into the second supply part 20 , so that the second content 22 remaining in the second supply part 20 is reduced. Therefore, it is easy to avoid liquid droplets at the tip of the discharge unit 40 .

In addition, the discharge device 100 may start supplying the first content 12 to the first supply unit 10 while the second content 22 is poured into the second supply unit 20 . Thereby, it is possible to start increasing the pressure while injecting the second content 22 into the second supply part 20, and it is possible to prevent the second content 22 from flowing toward the first supply part 10 side.

The liquid immersion conduit 152 extends to the inside of the aerosol container 150 and has a flow path for sucking the contents of the aerosol container 150 . The length of the liquid immersion conduit 152 may also be changed according to the type of contents of the aerosol container 150 . The liquid immersion conduit 152 may also extend until near the bottom of the aerosol container 150 .

The casing 154 is connected to the liquid immersion conduit 152 . The casing 154 accommodates the valve stem 112 and the valve stem elastic portion 114 . The housing 154 has a flow path for the content to flow from the liquid immersion conduit 152 to the valve stem 112 .

The installation cap 156 is arranged on the top surface of the airgel container 150 . The cap 156 is installed to fix the valve stem 112 and the housing 154 on the body of the aerosol container 150 .

Here, the standby state (b) is set between the avoidance state (a) and the discharge state (c). By setting the cam 91 at the standby angle, the valve stem 112 can be pushed to such an extent that the valve of the aerosol container 150 does not open, and the gap between the pressing part 110 and the valve stem 112 can be eliminated. Thereby, even if pressure in the opposite direction is applied to the aerosol container 150, the aerosol can will not fall off. That is, the movable part 93 can receive the force by the pressure in the opposite direction.

On the other hand, when the cam 91 is not at the standby angle, if it is at the avoidance angle, the pressing portion 110 is not used to push the valve stem 112 and a gap is generated between the pressing portion 110 and the valve stem 112 . Therefore, when a reverse pressure is applied, the aerosol container 150 may fall off from the pushing portion 110 and the contents may leak out.

FIG. 6B is a timing chart showing the driving state of the discharge device 100 . Graph A is a timing table showing the driving of the discharge drive unit 90a of the aerosol container 150a. Graph B is a timing chart showing the driving of the discharge drive unit 90b of the aerosol container 150b.

At time T0, both the discharge drive unit 90a and the discharge drive unit 90b are in the avoidance state (a). At time T1, the discharge drive unit 90a shifts from the avoidance state (a) to the standby state (b) to set the aerosol container 150a in the standby state (b). At time T1, the discharge drive unit 90b shifts from the avoidance state (a) to the discharge state (c) to set the aerosol container 150b in the discharge state (c). In this way, while the aerosol container 150b is set in the discharge state (c), the aerosol container 150a is set in the standby state (b), so the influence of liquid leakage in the aerosol container 150a can be avoided.

Thereafter, at time T5, after the discharge drive unit 90b sets the aerosol container 150b to the standby state (b); at time T6, the discharge drive unit 90a sets the aerosol container 150a to the discharge state (c). While the aerosol container 150a is set in the discharge state (c), the aerosol container 150b is set in the standby state (b), so the influence of liquid leakage in the aerosol container 150b can be avoided. Thereafter, at time T9, both the discharge drive unit 90a and the discharge drive unit 90b may be placed in the avoidance state (a).
